Pulling away from runner-up Brad Keselowski over a green-flag run that consumed the final 72 laps, Busch won his sixth NNS event at the .533-mile short track. The victory was his ninth of the season and the series-record 60th of his career.

In winning for the 15th time at Bristol across NASCAR's top three series, Busch led 228 of 250 laps. The pole he won earlier in the day was his sixth of the season. Each time, Busch has gone on to win the race.

When Busch wrecked during Cup qualifying, many in the crowd cheered loudly. But Busch found perhaps the best revenge -- winning, and winning emphatically, scoring his 19th Nationwide Series perfect driver rating of 150.0.

"It comes from preparation, it comes from the shop, it comes from practice here," Busch said in explaining his dominance. "(Crew chief) Adam (Stevens) and I - we work real well together. Those guys work hard. Today, just a great car and great job by these guys putting together such a great Monster Energy Camry.

"It was a lot of fun tonight. It's cool when you can start up front, lead laps like that, but yet you have some battles with holding off the 22 (Keselowski) and having to pass the 32 (Larson, who led briefly after a restart on Lap 110) -- just a fun day. Whether you're cheering of booing, don't matter. We're here to win races, take trophies home and that's what we're going to try to do (Saturday) night, too."

"We were close, just not quite good enough," Keselowski said ruefully. "We just came up a little bit short. Obviously, on the track, I didn't have quite enough speed to get by Kyle."

Brian Vickers' wreck out of Turn 4 on Lap 167 continued a succession of trouble for series championship contenders. By the time Vickers nosed into the inside wall on the frontstretch, Regan Smith already had lost two laps pitting under green because of a loose wheel.

Sam Hornish Jr., the points leader entering the race, also struggled, losing a lap to Busch on the track. Shortly after a restart on Lap 179, Hornish's Ford slapped the outside wall in Turn 4 and fell back to 13th, one lap down.

Elliott Sadler also went a lap down with an ill-handling car but got it back with a free pass as the highest-scored lapped car after the caution for Vickers' accident. Sadler finished 10th, two positions ahead of Hornish. Smith was 21st and Vickers 24th.

Notes: Hornish retained the series lead by six points over Dillon... In the battle for the owners' championship, Busch's No. 54 Joe Gibbs Racing Camry cut the lead of Keselowski's No. 22 Ford from 22 points to 16.
